Evidence for Two Separate Purinergic Responses in Paramecium tetraurelia: XTP Inhibits Only the Oscillatory Responses to GTP


The purine nucleotide GTP causes a complex behavioral response and two distinct electrophysiological responses in the ciliated protozoan Paramecium tetraurelia. One of the two electrophysiological responses is an oscillating current that is responsible for the repeated backward swimming episodes that constitute the behavioral response to GTP. The second… (More)
